AfterFast, Reliable AC Installation Across Wimberley
Most AC installations in Wimberley run $3,500-$7,500 for a complete system replacement, and every job starts with a written, fixed-price quote before we unload a single tool. We’re Coldharbour Heating & Air, and our AC Installation team designs systems specifically for the Hill Country’s heat-pump-only fuel reality, its sloped limestone building sites, and the boom-bust usage patterns of vacation homes that sit dark for weeks then run flat-out through July weekends. Call (817) 402-2972 for a free estimate - we’ll come to your property, measure the actual cooling load, and hand you a written price that doesn’t change at the door.
Wimberley sits in the Blanco River valley at roughly 1,000 feet elevation, and that valley topography does real work on your HVAC system. Summers are brutally hot and humid enough to matter. Winters trap cold air when Arctic intrusions push south - Winter Storm Uri in February 2021 exposed how many homes here were fitted with bare-minimum heating not rated for sustained sub-freezing conditions. Our crews serve Wimberley locally, with dispatch and scheduling coordinated from our Dallas-Fort Worth office. We know the difference between a mid-century ranch on a slab near Wimberley Square and a cedar-and-limestone custom build off Ranch Road 12 with pier-and-beam foundations and multi-zone ductwork that was never properly commissioned.
Why Coldharbour Heating & Air Is Wimberley’s Preferred AC Installation Company
We’ve been at this since 2003, operating as an independently owned member of the Kingswell network. The Kingswell Guarantee isn’t a slogan - it’s four written promises on every job: a price before the work starts, a firm arrival window, a clean job site, and our 365-Day Done Right Promise. If a repair fails within a full year, we come back and make it right at no charge. That guarantee is written down before the technician leaves, not offered as a verbal afterthought.
Our technicians are background-checked, uniformed, and trained on nine major residential HVAC brands - Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. When we pull up to a Wimberley home, we already know what we’re looking at. We’ve replaced systems in the ranch houses along River Road, commissioned multi-zone heat pumps in the vacation cabins near Blue Hole Regional Park, and solved airflow problems in 1990s Hill Country builds where the original ductwork was sized for a smaller unit than today’s cooling loads demand.
A live person answers our phones 24 hours a day, 7 days a week. No voicemail trees. No after-hours runaround. And we don’t change the price at the door - the written quote you approve is the price you pay.
Furnace Installation in Wimberley
Furnace Installation in Wimberley means working within a fuel reality that reshapes every conversation: this town has no natural gas distribution infrastructure, so every heating system runs on propane or electricity. That changes tonnage calculations, defrost strategies, and backup-heat planning on nearly every job we design. A propane furnace paired with a straight-cool condenser is one path. A heat pump with electric strip backup or a dual-fuel propane assist is another. We walk through the operating-cost math with you, season by season, because the right choice for a full-time residence on Cypress Creek Road can differ sharply from what’s sensible for a vacation rental that sits empty from Labor Day to Memorial Day.
Propane vs. Heat Pump Sizing
Propane furnaces run hot and fast, which can overshoot setpoint in smaller Wimberley homes with poor envelope sealing. Heat pumps modulate more gradually but need proper defrost control for Hill Country humidity and occasional hard freezes. We size for the actual block load, not square footage divided by 500.
Vacation-Home Considerations
A furnace in a Wimberley vacation home that sits dormant for weeks needs different staging and filtration than a full-time residence. We specify systems that can handle the pollen surge when the unit fires up after a month offline, and we set controls to maintain minimum airflow during vacancy to prevent moisture buildup.
HVAC Installation in Wimberley
HVAC Installation in Wimberley covers the full replacement of both heating and cooling components - and here, that almost always means designing around a heat-pump-centric or propane-fueled system rather than the natural-gas setups common in San Marcos or Kyle. We start with a Manual J load calculation that accounts for your home’s actual orientation, insulation, window performance, and duct leakage. On sloped limestone lots, we also evaluate outdoor unit placement for drainage, airflow, and winter wind exposure. A system dropped on the shaded north face without freeze protection or proper defrost strategy is a liability we saw exposed too often during Winter Storm Uri.
Load Calculation vs. Rule of Thumb
Too many Wimberley homes were originally sized by contractors who divided square footage by a fixed number and called it done. The result: upstairs zones that short-cycle all August, never pull humidity below 60%, and burn out compressors prematurely. We measure everything.
Duct System Evaluation
Older Wimberley properties often have legacy duct systems that can’t deliver the airflow a modern SEER2 evaporator coil requires. We test static pressure and airflow at each register before specifying equipment. Choking a new high-efficiency unit with undersized ducts wastes the investment.
Trusted Brands We Service in Wimberley
We carry and install Goodman, Rheem, and Daikin systems with local parts availability for Wimberley customers, which means faster turnaround when a warranty component is needed and no waiting on freight from Houston or Austin. Our technicians are factory-trained on these lines and on Carrier, Trane, Lennox, York, Bryant, and American Standard - so whatever system is already in your home, we can work on it, match it, or replace it with a compatible upgrade. We stock common heat-pump components and high-MERV filter sizes suited to Wimberley’s cedar pollen loads, because a filter that works in Dallas often cakes shut in December here.
Common AC Installation Problems We See in Wimberley Homes
- Square-footage sizing instead of real load calculation. Multi-zone vacation homes get short-cycling systems that run high static pressure and never reach setpoint on holiday weekends when the whole extended family shows up. We see this in rental cabins near Jacob’s Well and in older builds off FM 2325.
- Outdoor units placed on sloped limestone without freeze protection. The shaded side of a Hill Country build looks logical in July, but winter wind and trapped cold air strain heat-pump defrost cycles. After Uri, we now specify elevated pads, wind baffles, and dual-fuel backup on exposed installations.
- Undersized legacy duct in mid-century ranch houses. The original 1960s or 1970s ductwork was designed for a 3-ton unit with lower airflow requirements. A modern SEER2 coil needs more air across it, and when the ducts can’t deliver, the system underperforms from day one.
- Uncommissioned multi-zone systems in custom builds. We regularly find zone dampers that were never balanced, thermostats that weren’t configured for dehumidification mode, and static pressures that read above 0.8 in. w.c. because nobody tested the finished job. The homeowner pays for a premium system that performs like a budget unit.

FAQs About AC Installation in Wimberley
Yes. A vacation home in Wimberley needs a system that can recover quickly from setback temperatures during peak summer demand, with controls that maintain minimum airflow during vacancy to control humidity and prevent mold. We often specify two-stage or variable-capacity equipment with dehumidification-enabled thermostats, and we set higher-MERV filtration to handle the cedar pollen load that accumulates during dormant periods. Call (817) 402-2972 and we’ll design for your actual occupancy pattern.
Most Wimberley properties benefit from a heat pump as the primary heat source, with electric strip backup or a propane furnace for dual-fuel operation during the coldest nights. Heat pumps handle our typical winter efficiently, and the lack of gas infrastructure means you’re not fighting fuel availability. We run operating-cost projections using local electric and propane rates so you can see the crossover point. The right choice depends on your home’s insulation, your tolerance for backup-fuel delivery, and whether the property is full-time or seasonal.
It affects how we spec the new system. We routinely find coils and blower wheels in Wimberley vacation homes caked with fine cedar pollen after a winter unattended. On replacement jobs, we include thorough coil and cabinet cleaning, upsize filter racks to accept 4-inch or 5-inch media filters with higher MERV ratings, and set blower profiles that maintain adequate airflow even as filters load. The pollen here is real - December through February produces some of the highest airborne counts in the country - and ignoring it in the design means reduced capacity within two seasons.
We zone by load and usage pattern, not by room count. A 3,500-square-foot cedar-and-limestone build with great-room exposure, a master wing that sleeps cooler, and a guest wing used only on weekends needs independent control for each area. On a recent job off Ranch Road 12 north of Wimberley Square, we replaced poorly zoned systems that short-cycled all August, ran a full block load calculation, installed two-stage heat pumps with dehumidification-enabled Carrier thermostats, rebuilt undersized return drops, and commissioned to under 0.5 in. w.c. static pressure. The house now holds 48% RH on a 100°F afternoon. Zones are only as good as the ductwork and controls behind them.
Higher-SEER2 systems deliver their value through longer run times at lower capacity, which means better humidity control during Wimberley’s sticky summer afternoons and quieter operation when you’re trying to hear the Blanco River over the backyard. The payback period shortens if you’re full-time; for a vacation rental used eight weekends a year, the math differs. We’ll run the operating-cost comparison using your actual electric rate and occupancy pattern so the decision is grounded in numbers, not pressure.
